Floatingip access from host is broken,

I deployed devstack with odl using carbon and new netvirt odl-netvirt-openstack, Instance is not accessible from host via fip.

I am using master version of openstack neutron and networking-odl, It is broken with ocata + carbon as well. It is affecting some gate jobs in openstack networking-odl which are trying to test public network connectivity.

I've tried berylliyum + legacy netvirt it works.

steps to reproduce
------------------

once you have devstack up with private and public (external network) created.

1. Make sure you have public network interface ( in devstack case it will
be Public network)
2. Add icmp and tcp on port 22 rule to security group.
3. Create an vm with security group you added rules to.
4. Create an floatingip using public network.
5. Attach floating ip to vm
6. Ping or ssh to vm using floatingip.

vm is not accessible.
